Some GM products also incorporate the oil sender switch into that circuit for fuel pump, so that in case of an accident, engine shuts off, oil pressure drops, in turn, shuts off power to fuel pump. May be worth a look at what your getting for oil pressure, as well as checking switch/sender.

Try using a good fuel line/injector cleaner Seafoam is a good one. If this does not help you may have tone or more clogged injectors. Clean these out and you should be good to go. tTo see Seafoam in action goto you tube type Seafoam into the search box.

sounds like a short in the wiring from the fuse and the fuel injector junction block. GM like most fuel injection systems control injector firing by the computer providing ground to each injector in pairs or individually. The fuel injector fuse provides power to the injectors using splices therefore enabling one wire to feed 6 injectors. A shorted wire at any of these wires will blow the fuse. On one rare incident I found a faulty computer caused the fuse to blow. A shorted injector will just cause a rough running problem due to the injector stuck either open or closed.

On the plus side, when you are finished, you will have a new control system! On the negative side, you just spent more money on parts than if you'd have just taken it to a dealer! I hope you tested those components and determined they have failed. Any codes?
Seems like the only thing you missed is the coil and the temp sending unit (just for laughs, unplug it and see if it stalls out at the same time), or possibly a security system malfunction. Get a decent volt/ohmeter and a vehicle specific manual such as chiltons or haynes. Do some testing, hot and cold and compare your results.You need to determine what is shutting down (fuel, spark or both) Once you develop a "picture" regarding what is happening, you will be more able to find a solution. I can't give you a "fix" on this one only because to properly identify the problem, I'd need to do the same testing I suggested.

if the injector fuse is blown then the car won`t start as its not getting fuel into the motor to fire.if the fuse keeps blowing then you could have an injector/s that is drawing too much or the injector driver in the ecm may not be any good and needs replacing or a used ecm.it could be a short some where in the wiring for the injector system that is going to ground.
